Poster: Triphenyl Phosphate Plasticiser in Heritage Collections: Object and Health Impacts

Lisa Russ, University of Canberra

Triphenyl phosphate (TPP) is a common plasticiser and fire retardant used in the manufacture of plastics, including motion picture film. TPP migrates from the plastic matrix as it deteriorates, often presenting as crystals on the surface. As TPP crystals disintegrate and are disturbed through handling they can be inhaled, ingested, and absorbed through the skin. TPP is a potential endocrine disruptor that interferes with hormonal function to influence obesity, affect child development and behaviour, and sperm concentration. As the prevalence of plastic increases in heritage collections, staff may be at an increased risk of TPP exposure. This poster presents preliminary results from FTIR object testing and an online survey canvasing Australian and international heritage institutions to determine TPP’s presence in the heritage sector and inform risk mitigation strategies for safe work practices. Results indicate cellulose acetate as a polymer of interest and inhalation as an exposure pathway in heritage workers.
